48AT
- Can I use the 48AT attenuator with multimode fibers?
  No you should not. If used with single-mode fibers the fibers serve as a mode filter and the exiting beam is still Gaussian with reduced power. In case of a multimode fiber not only the power is attenuated but also the intensity distribution ex fiber is affected.
